Description

Technical Field

[0001] This utility model belongs to the field of tungsten and molybdenum product processing technology, specifically relating to a high-temperature tensile testing device for tungsten and molybdenum products. Background Technology

[0002] In modern industry, tungsten and molybdenum products are widely used in many key sectors such as aerospace, electronics, machinery manufacturing, and energy due to their excellent properties, including high melting point, high strength, and good electrical and thermal conductivity. As industries continue to demand higher product performance, the mechanical properties of tungsten and molybdenum products under high-temperature conditions have become a crucial factor affecting product quality and reliability.

[0003] Patent application CN202222588990.8 discloses a high-temperature tensile testing device for tungsten and molybdenum products. During installation, the tungsten and molybdenum product is inserted into a hollow jaw to enter the testing chamber. After locking the hollow jaw, it clamps and secures the product. Then, the product is inserted into a triangular jaw, which clamps and secures the other end of the product. Installation does not require opening the chamber, enabling rapid installation and improving the speed of high-temperature tensile testing. An electric push rod moves a central plate, which in turn moves a pressure sensor. The pressure sensor then moves the triangular jaw, applying a tensile force to the tungsten and molybdenum product. This invention ensures stable movement of the triangular jaw, guaranteeing uniform force on the product during testing and thus ensuring the accuracy of the test data.

[0004] The tensile testing device for tungsten and molybdenum products proposed in the aforementioned document has two sets of fixed-position jaws that cannot be moved. Therefore, the aforementioned document can only be used to perform tensile testing on tungsten and molybdenum products of a specific length. It is inconvenient to adjust and difficult to quickly adapt to testing tasks with different specifications and requirements. Moreover, it can only perform torsion measurement and cannot comprehensively test the tensile properties of tungsten and molybdenum products. Utility Model Content

[0026] Example

[0027] Reference Figure 1-4 This is an embodiment of the present invention, which provides a high-temperature tensile testing device for tungsten and molybdenum products, comprising:

[0028] The tensioning assembly 100 includes a base 101, a housing 102 fixedly connected to the upper end of the base 101, a lead screw 103 rotatably connected to the side wall of the housing 102, a connector 104 threadedly connected to the side wall of the lead screw 103, and a mounting hole 105 provided in the middle of the connector 104. A through hole structure that mates with the mounting hole 105 is provided in the middle of the upper end of the housing 102.

[0029] The heating assembly 200 includes a sleeve 201 fixedly connected inside the connector 104, an electric heating element 202 fixedly connected to the side wall of the sleeve 201, and a temperature control switch 203 fixedly connected to the side wall of the connector 104. The end of the sleeve 201 is connected to the middle through hole of the housing 102, and the electric heating element 202 is electrically connected to the temperature control switch 203 through a wire.

[0030] The base 101 serves as the fundamental support component of the equipment, providing a stable mounting platform for other components. The lead screw 103 is rotatably connected to the side wall of the housing 102. The rotation of the lead screw 103 converts rotational motion into linear motion, thereby driving the connecting member 104 to move linearly along the lead screw. The mounting hole 105 in the middle of the connecting member 104 is used to mount the tungsten-molybdenum product sample to be tested, ensuring accurate positioning of the sample during the tensile testing process. The end of the sleeve 201 is connected to the through hole in the middle of the housing 102. Current flows through the heating element 202, generating heat to heat the sample inside the sleeve 201. The temperature control switch 203 monitors the temperature inside the sleeve 201 in real time and automatically controls the on / off state of the heating element 202 according to the set temperature value, thereby precisely controlling the heating temperature and ensuring that the sample undergoes tensile testing in the required high-temperature environment.

[0031] Specifically, the tensioning assembly 100 also includes a stepper motor 106 fixedly connected inside the housing 102, and the output end of the stepper motor 106 is fixedly connected to the end of the lead screw 103.

[0032] Among them, the stepper motor 106 can precisely control the rotation angle and speed, thereby achieving precise control of the moving distance and speed of the connector 104 to meet different tensile testing requirements.

[0033] Furthermore, the tensioning assembly 100 also includes a support rod 107 fixedly connected to the upper side wall of the housing 102, and a fixing seat 108 fixedly connected to the end of the support rod 107. The fixing seat 108 has a guide hole 109 in the middle position that cooperates with the mounting hole 105. The side wall of the fixing seat 108 has a bolt hole structure. The guide hole 109 has the same size as the mounting hole 105.

[0034] The support rod 107 is fixedly connected to the upper side wall of the housing 102, serving to support the fixing seat 108. The guide hole 109 works in conjunction with the mounting hole 105. It guides and positions the sample installed in the mounting hole 105, ensuring that the sample is stretched along a straight line during the stretching process and avoiding deviation.

[0035] Preferably, the tensioning assembly 100 further includes a rotating rod 110 rotatably mounted inside the connector 104, and a locking block 111 threadedly connected to the side wall of the rotating rod 110. The end of the locking block 111 is inserted into the side wall of the mounting hole 105. The rotating rod 110 has a double-ended screw structure. The locking blocks 111 are symmetrically mounted on both sides of the center of the rotating rod 110, and the side wall of the end of the locking block 111 is provided with anti-slip texture.

[0036] By rotating the rotating rod 110, the clamping blocks 111 symmetrically installed on both sides of its center can be moved. The clamping blocks 111 will move towards the center or the outside of the mounting hole 105, thereby clamping or releasing the sample to be tested. The end sidewall of the clamping block 111 is provided with anti-slip texture, which can increase the friction between it and the sample and prevent the sample from sliding during the stretching process.

[0037] Preferably, the tensioning assembly 100 further includes a knob 112 rotatably mounted on the outer wall of the connector 104, the knob 112 being fixedly connected to the end of the rotating rod 110.

[0038] The operator can easily control the rotation of the lever 110 by turning the knob 112, thereby operating the clamping and releasing action of the locking block 111.

[0039] When performing high-temperature tensile testing on tungsten and molybdenum products, first place the sample to be tested in the mounting hole 105, then turn the knob 112 to rotate the rotating rod 110. Since the locking block 111 is threadedly connected to the side wall of the rotating rod 110, the rotation of the rotating rod 110 will cause the locking block 111 to move towards the center of the mounting hole 105, using the anti-slip texture at the end to clamp the sample.

[0040] Next, the desired heating temperature is set using the temperature control switch 203. After the equipment is turned on, the temperature control switch 203 controls the current to flow through the heating element 202, and the heat generated by the heating element 202 heats the sample inside the sleeve 201. When the internal temperature of the sleeve 201 reaches the set value, the temperature control switch 203 automatically cuts off the power supply to the heating element 202 to maintain a stable temperature.

[0041] Next, the stepper motor 106 is started, and its output drives the lead screw 103 to rotate. Since the connector 104 is threaded onto the side wall of the lead screw 103, the rotation of the lead screw 103 causes the connector 104 to move axially along the lead screw 103, thereby applying a tensile force to the sample mounted therein. The guide hole 109 on the fixing seat 108 guides the sample, ensuring that the sample is stretched along a straight line during the stretching process. During the stretching process, the deformation and fracture of the sample are observed, relevant data are recorded, and the high-temperature tensile test is completed.

[0042] In summary, by precisely controlling the rotation of the lead screw via a stepper motor, and thus accurately controlling the movement of the connecting parts, precise adjustment of the tensile force and speed can be achieved. This meets the requirements for high-temperature tensile testing of tungsten and molybdenum products with different specifications and requirements, improving the accuracy and reliability of the test results. The heating element, in conjunction with the sleeve, can quickly heat the sample to be tested. The temperature control switch monitors and precisely controls the temperature in real time, ensuring that the sample is subjected to tensile testing in a stable high-temperature environment, simulating the high-temperature conditions in actual use, making the test results more practically valuable. The clamping and releasing of the locking blocks is controlled by rotating the knob, making operation convenient and quick, enabling rapid sample installation and removal, improving testing efficiency. Simultaneously, the anti-slip texture at the end of the locking blocks effectively prevents the sample from slipping during the tensile process, ensuring smooth testing.
